Recalibrating Your MC-II
If your MC-II was purchased as a system, it was calibrated at the factory
with its companion NuFlo turbine flowmeter. Verify the calibration set-
tings to ensure that no further calibration is required prior to use.
If you purchased a stand-alone MC-II without a flowmeter, the MC-II
must be calibrated before being operated.
The following information is needed to calibrate the MC-II:
• unit of measure for volume
• flowmeter calibration factor (in pulses per gallon)
• unit of measure for flow rate
The calibration procedure is explained in detail below.
1. Press and hold
ACCESS
for 3 seconds, then release, to enter Cali-
brate mode. Following a quick diagnostic test, Prog.no will appear
in the top display and the version number of the firmware will appear
in the bottom display for 1 to 2 seconds.
The tot.Eng menu will then appear in the top display. The factory
default volume unit - bbL - will appear in the bottom display.
IMPORTANT: If the pulse output option is in use, you must select
uSEr
as the unit of measure for volume. Any other selection will
cause the pulse output to yield an incorrect number of pulses.
2. To select a unit of measure for volume: bbl, gal, m
3
, liter, or user-
defined, press INCREMENT repeatedly until the appropriate unit
of measure appears in the bottom display. Press ENTER/STEP to
accept the selection.
• If you select a preprogrammed unit, the Pu.P.gAL menu will ap-
pear in the top display, allowing you to enter the calibration factor
of your companion flowmeter. The MC-II will automatically
calculate the divisor. Proceed to Step 3 for further instruction.
• If uSEr is selected, Ent.diV will appear in the top display,
prompting you to enter a calculated divisor in terms of the unit
specifications. Enter the divisor, from right to left, using the IN-
CREMENT key to select each digit, and the ENTER/STEP key
to accept each digit selection. Then proceed to Step 4 for further
instruction. An example of MC-II calibration with user-defined
units is provided on page 20.
